To all whom it may concern:

Be it known that we, ROBERT E. FRAME and Jonx M. Bpmmo, residing at St. Louis, Missouri'yand being citizens of the United States, have invented certain new and useful Improvements in Truck-Bolsters,-

of which the followingis a full, clear, and

exact description, such as will enable others skilled in the art to which it appertains ing had to the accompanying drawings, which illustrate the preferred form of the invention, though it is to be understood that the invention is not limited to the exact details of construction shown anddescribed, as it is obvious that various modifications thereof will occur to persons skilled in the art.

In said drawings: Figure 1 is a plan view of improved bolster. Fig. 2 is an elevational view thereof. Fig. 3 is a, transverse sectional view, the section being taken 'on line3-3 of Fig. 1. Fig. 4 is a transverse sectional view, the section being taken on line H of Fig. 1. Fig.- 5 is a diagrammatic elevationalidew showing the principal bolster girder member in full lines as it comes from the mills'and showing in dotted lines a central vertical opening which is formed through the top and bottom flanges and the web portion ofthe girder, and showing in otherdotted lines the lines of cutting indicating the parts of the girder web which are severed from the principal. web portions.

The object of the invention is to provide a simple, strong and durable bolster formed primarily of a. single rolled girder of H section with the web vertically disposed and the flanges horizontally disposed. While an H section is specified, because this section is considered as best adapted for the purposes. an I-beam may be substituted for the H section, the principal difference between the two being the width of the horizontal flanges at the top and bottomof the girder. Before attaching the auxiliary parts to this section necessary to complete the holster a' vertical opening, indicated at l. in Fig. 5, is formed through the top flange 2, the web 3 and bottom flange 4, this opening extend inp; entirely through the girder, while the web is cut through along. the oblique lines 5 and the horizontal lines 6 forming exten- 510m at said oblique lines, to the ends of to make and to use the same, reference bethe web. The metal-of the web is also cut away from the lower flanges 4 so that the portion 7 of the web may be' removed. After this is done the lower flange 4 is bent upwardly to position contiguous the new lower edge of the web 3 as indicatedb the numeral 7" in.Fig. 2, the metal of the ange being bentto form the oblique portion 8 between the center part of the bolster and the inner line of the spring seats, and extends thence in a horizontal direction outwardly. This is done with both ends of the flange 4 and the bottom cover plate 9 is placed in position, bent to the proper form, and connected by means or the rivets 10 with said bottom flanges, after which the centrally disposed vertical castings or pre ings 11, one on each side of the'web 3, are secured together and to said web'by means of horizontally disposed rivets 12, said cen-: tral members forming pin socketsin the completed bolster and serving as strengthen;- ing members of said bolster.

As noted in Figs. 2 and 4:,rivets 13 ex tend downwardly through the laterally projecting flanges 14 of the member 11 through said flanges, through the bottom flange 4; of the girder, and through the bottom cover plate 9 of the bolster. Y

It is to be notedthat substantially with in the range of projection of flanges 14 the bottomflange of the girder remains in position as an integral part of the girder. and connected with the web thereof.

The top flanges 2 are integral with-the web 3 and are continuous from end to end of the bolster and to these top, flanges are secured the bolster center bearings 16, which may be of any preferred type or construction. Secured also to these top flanges are sidebearings 17 while angles 20 are connected with the web 3 at each end of the bolster and with the bottom flanges i; and

bottom cover plate 9 by rivets 21, as' best that the bottom flanges may serve as a continuons plate when bent into position shown in Fig. 2 instead of comprising sepa rated portions as indicated in F 3.

It is obvious that the centrally disposed members 11 extend from the lower flanges 4- to and in contact preferably with the upper flanges 2, therebyproviding continuous compression members between said flanges, which compri on membi-n-s independent of the web 3, serve, when placed in position,

as a pin sock It will be ob erred when the flanges t are severed vertically from the part 7 and the part 7 is removed, said flanges will be spaced apart by removal of the material therebetweiai of the part 7, and thus when the flanges t are bent upwardly they readily and naturally assume a position at either side of the remaining portions of the web of the H-scctioin as indicated in Fig. 3.

()lbourse, when the severance oi? the part 7 from the flanges t occurs horizontally in the 1 lanes of the upper races of the flanges, the integral formation of the flanges with respect to themselves and. the intervening ma erial of the web is n'niintainwl, and in such instance the flan are merely brought up to a position wit.) the material in the i'ncdian line between the. flanges in contact with the ren'iaining edge of the web left by the removal of the part 7.
